Abstract
A side rearview mirror control system for a vehicle that automatically changes a rear viewing angle of a side rearview mirror. The control system receives various vehicle inputs to determine if and when a vehicle operator will turn the vehicle, make a lane change, merge into a lane of traffic, etc. The system pivots the mirror to eliminate a potential blind spot during these conditions. In one embodiment, the rear view mirror control system receives input signals from a vehicle hand-wheel angle sensor, a vehicle yaw rate sensor, a vehicle speed sensor, a turn signal indicator, a global positioning system (GPS) receiver and map information to determine whether the vehicle is turning or will be turning.
